Europe is experiencing an intense and persistent heatwave, with forecasts showing a ‘heat dome’ and extreme heat likely extending into mid- and late August 2025, especially across the Iberian Peninsula, western, and central Europe, including the UK. The ongoing drought and persistent high-pressure patterns have prompted alerts and fire bans, as rainfall remains below average across most of the continent[1][3].
Meanwhile, the United States is facing a varied weather pattern at the start of August. Extreme heat is setting new daily temperature records in the Desert Southwest, and fire weather concerns continue across this region due to hot, dry, and windy conditions. In contrast, the northern and central Plains to the Mid-Mississippi Valley and parts of Minnesota are at marginal risk of severe thunderstorms, with isolated strong to severe storms expected through tonight. On Friday, the northern Great Plains and Upper Midwest, particularly the Red River Valley, face an enhanced risk of scattered severe thunderstorms[4][6].
Looking at broader patterns, the western and parts of the eastern US will likely see above-normal temperatures for August overall, while central areas may experience near-normal conditions. The tropics are becoming more active, with the National Weather Service monitoring the potential for tropical system development towards mid-August and above-average rainfall predicted for areas near Bermuda and the eastern US coastline[8].
Globally, the climate outlook for July–September 2025 indicates continued neutral El Niño–Southern Oscillation (ENSO) conditions. Sea-surface temperatures remain above normal in most ocean basins except the near-equatorial central Pacific. Above-normal land temperatures are projected for nearly all regions during this period, while the Indian Ocean Dipole and Atlantic SSTs should remain close to average[7].
Additionally, a G2 (Moderate) geomagnetic storm watch has been issued for August 8, and a G1 (Minor) watch for August 9, due to a combination of a coronal mass ejection and high-speed solar wind streams interacting with Earth’s magnetosphere[5].
